retrovirus
*Love you, put this on 3 down!! buahahaha
Well a virus can duplicate many copies of itself by attaching itself to a cell, any cell, and using the cells machinery they inject their DNA and later the cell bursts and copies of the virus come out. When a bacteria duplicates it uses binary fission. Binary fission is when a bacteria splits itself into two and makes to copies of itself. Hope I answered your question.

Solar Panels or Solar Cells
Virus require a host to carry out the most of the characteristics of living organisms. In almost cases, viruses require a host to reproduce (by hijacking the cells of the host and using its DNA to make copies of itself) and also receive the bulk of their energy from the host.
makes food using photsynthisis, only found in plant cells
The body expels viruses by itself, using white blood cells.
The use of stem cells is not unethical in and of itself, the ethics component revolves around the source of the stem cells and the concern that fetuses will be produced and intentionally destroyed in order to obtain stem cells.
